Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If display means comprises several luminaire elements that can be switched on or off in a time-shifted manner, then the detection of drive status becomes easy and quick, but the device complexity increases
Solution Approach 1:
The patent applies color changes by using luminaire elements that emit electromagnetic waves in different wavelength ranges (colors) to indicate different drive states. The control unit switches these luminaire elements on or off in a time-shifted manner to visually represent the drive status of drive means, making detection easy and quick while using a relatively simple display structure.
2Device complexity
If one display unit is assigned to several components of the manipulator device, then the device complexity is reduced, but it becomes difficult to quickly identify current problems
Solution Approach 1:
The patent applies segmentation by dividing the display function into multiple luminaire elements within a single display unit, where each luminaire element can be independently controlled to represent different drive states of different drive means. This segmentation allows one display unit to monitor multiple components while maintaining clear problem identification through distinct visual indicators for each drive means.
3Difficulty of detecting and measuring
If luminous elements emit electromagnetic waves in different wavelength ranges, then different drive states can be easily detected, but the manufacturing complexity increases
Solution Approach 1:
The patent applies parameter changes by utilizing luminaire elements that can emit electromagnetic waves in different wavelength ranges (different colors) to represent different drive states. The control unit manages these different wavelength emissions by switching luminaire elements on or off in a time-shifted manner, enabling easy differentiation of drive states while using standard manufacturing approaches for multi-color LED or luminaire assemblies.
